OBJECTIVETo observe the clinical efficacy differences among warming-promotion acupuncture, regular acupuncture and psychological care for post-earthquake depression.

METHODSNinety cases of post-earthquake depression in Gansu province were randomly divided into a warming-promotion acupuncture group, a regular acupuncture group and a care group, 30 cases in each one. The psychological treatment was applied in the care group; the regular acupuncture at Baihui (GV 20), Sishencong (EX-HN 1)), Fengchi (GB 20), Shenmen (HT 7), Yang-lingquan (GB 34), Taichong (LR 3) and Sanyinjiao (SP 6) was used in the regular acupuncture group; based on the treatment of regular acupuncture group, the warming-promotion acupuncture was applied in the warming-promotion acupuncture group, once a day. Ten days were taken as one course with an interval of two days between two courses. Totally 3 treatment courses were completed. The Hamilton depression (HAMD) scale before and after treatment in each group was observed while the efficacy was analyzed.

RESULTSAll three treatments were effective for depression. The total cured rate was 86.67% (26/30) in the warming-promotion acupuncture group, which was obviously superior to 50.00% (15/30) in the regular acupuncture group (P < 0.01) and 33.33% (10/30) in the care group (P < 0.001). After the treatment, the score of HAMD was all reduced in three groups, in which the effect in warming-promotion acupuncture group was superior to that in the regular acupuncture group and care group (9.02 +/- 2.37 vs 10.73 +/- 2.28 and 11.05 +/- 2.01, P < 0.05, P < 0.01).

CONCLUSIONThe warming-promotion acupuncture has positive effect on post-earthquake depression, which has special effect and is worthy of clinical generalization and application.

Objective:To investigate the clinical significance of dynamic analysis of plasma brain natriuretic peptide in patients with dilated cardiomyopathy with chronic heart failure.Methods:Ninety patients with dilated cardiomyopathy with chronic heart failure admitted into our hospital firom March 2012 to March 2016 were divided into group A (20 cases),group B (38 cases),and group C (32 cases) according to the NYHA grading.The plasma BNP levels and LVEF,LA,LVEDD,and LVESD in the three groups were detected and compared.The correlation of plasma BNP and cardiac function and ultrasonic cardiogram indexes were analyzed.And the capability of plasma BNP and LVEF in diagnosis of patients were analyzed and compared.Results:The plasma BNP level in group C was markedly higher than that of group A and group B (P＜0.05),and that in group B was much higher than that of group A (P＜0.05).And LA in group C was significantly higher than that of group A (P＜0.05),while differences in LVEF,LVEDD,and LVESD were not obvious (P＞0.05).The plasma BNP was positively correlated to NYHA grading,but had no significant correlation with the LVEF,LVEDD,LVESD,and LA (P＞0.05).Based on results of receiver operating characteristic curve analysis,plasma BNP =523.5 pg/mL was the threshold value for identification of patients with NYHA Ⅲ and Ⅳ (AUC=0.901,P＜0.001),while LVEF had not the capability (AUC=0.392,P=0.276).Conclusion:Detection of plasma BNP level had important clinical significance on diagnosis,screening and cardiac functional grading of patients with dilated cardiomyopathy with chronic heart failure.

Purpose To investigate the diagnostic value of dual energy CT spectrum curve combined with CT morphology in central lymph node metastasis of papillary thyroid carcinoma (PTC).Materials and Methods Thirty-one PTC patients who accepted dual energy CT double-phase enhanced scan before surgery were analyzed.Central lymph nodes with short diameter ＞ 5 mm were labelled using axial plus 3D positioning.Preoperative labelled lymph nodes were collected and marked during operation.The CT morphology of metastatic lymph nodes was analyzed.The spectrum curve slope (K) difference between metastatic and non-metastatic lymph nodes of arterial-phase and venous-phase primary lesion was compared.The critical K value and the diagnostic efficacy of K value combined with morphology were obtained according to receiver operating characteristic (ROC) curve.Results A total of 73 central lymph nodes were obtained from 31 patients,among which 51 were metastatic and 22 were non-metastatic.There was no significant difference in K value between metastatic and non-metastatic lymph nodes of arterial phase group (P＞0.05).While,there was a significant difference in K value between metastatic and non-metastatic lymph nodes of venous phase group (P＜0.05).For venous phase,the sensitivity and specificity of the K value in diagnosing central lymph node metastasis were 62.7％ and 59.1％,respectively,and combined with morphology,the sensitivity and specificity reached 76.5％ and 81.8％,respectively.Conclusion The K value of CT spectrum curve is of certain significance in predicting PTC central lymph node metastasis,and the K value combined with CT morphology can improve the accuracy of diagnosis.

Objective To discuss the clinical value of intravascular ultrasound (IVUS) in treatinginternal carotid arteries occlusion.Methods The patient was diagnosed with internal carotid artery occlusionthat was confirmed by CTA.Cerebral perfusion imaging showed that low perfusion area was consistent withischemic symptoms.Guided by IVUS,percutaneous transluminal angioplasty (PTA) was performed.By usingmicro-catheter coaxial technology,the micro guide wire was inserted in the carotid artery until it passedthrough the obstructed segment;After IVUS examination proved that the micro guide wire was in the truelumen of carotid artery,angiography through micro-catheter was carried out to confirm that the distal arterywas unobstructed;after adjusting the device position the embolism protector was placed.The plaque andlumen condition were assessed with IVUS,which was reevaluated after pre-expansion of balloon.After normaldirection blood flow was regained,the plaque stability was assessed with IVUS virtual organization sequence.Simple balloon dilatation therapy was adopted as the fibrous cap of plaque was in stable condition and thelumen stenosis rate was ＜40％.Results After balloon dilatation,the obstructed artery was reopened and theblood flow regained normal direction.IVUS examination showed that during the whole operation process thefibrous cap of plaque at the narrowed segment remained in stable condition,the lumen stenosis rate was ＜40％.Cerebral perfusion imaging revealed that after the treatment the low perfusion state was markedlyimproved.Conclusion IVUS plays an important guiding role in performing PTA for internal carotid arteryocclusion.This technique can increase the success rate of vascular recanalization and reduce the incidence ofcomplications.

Objective: To observe the clinical efficacy of combining two needling manipulations, Er Long Xi Zhu (two dragons playing with a pearl) and Guo Yan Re (heat produced to reach the eyes), in treating dry eye syndrome (DES) of lung-yin deficiency pattern. Methods: Fifty-six eligible DES patients of lung-yin deficiency were randomized into an observation group and a control group, with 28 cases in each group. Same acupoints were selected in the two groups: Cuanzhu (BL 2), Sizhukong (TE 23), Taiyang (EX-HN 5) and Fengchi (GB 20) were chosen as the major points and Feishu (BL 13) and Chize (LU 5) as the adjuvant. Er Long Xi Zhu and Guo Yan Re needling manipulations were applied in the observation group while twirling reinforcing manipulation was used in the control group. Treatment was conducted once per day in both groups, for two sets of 15 consecutive days at a 2-day interval. Changes in the symptom score, tear break-up time (BUT) and tear production were observed afterwards, and the clinical efficacy was also compared between the two groups. Results: The total effective rate was 92.8％ in the observation group, higher than 71.4％ in the control group, and the between-group difference was statistically significant (P<0.05). After treatment, the symptom score, tear BUT and tear production showed significant improvements in both groups (all P<0.05); the symptom score, BUT and tear production in the observation group were significantly different from those in the control group (all P<0.05). Conclusion: Given the same acupoint selection, combining Er Long Xi Zhu and Guo Yan Re needling manipulations can produce more significant clinical efficacy than twirling reinforcing manipulation in treating DES of lung-yin deficiency pattern.
